I'm not surprised: assemble-dart not working

[welopino]

I am using ceylon 1.3.2 and the corresponding ceylon-dart plugin.

running:

$ ./bin/ceylon assemble-dart --mode=js --out=first-assembly first

gives:

/tmp/ceylon-run-dart1838713660084194959/ceylon/dart/runtime/model/model.dart:836:3:

  ^^^^^^^^
Error: Compilation failed.
ceylon assemble-dart: dart2js reported an error.

The assembling tool of the java backend of version 1.3.2 doesn't work correctly either. Possibly those issues are related.

Ooops, looks like recent versions of Dart are not happy with using Function as an identifier. This should be easy to fix.

Thanks for the report.

Ok, it has nothing to do with https://github.com/ceylon/ceylon/issues/6956 ?!

[jvasileff]

Right, they don't share any code.

@welopino as a workaround, you can use Dart version 1.19.1.

Working example, using node to run a Ceylon/Dart program:

jvasileff@tau:tmp.Yboq6CCf$ cat source/simple/run.ceylon
"Run the module `simple`."
shared void run() {
    print("hello");
}

jvasileff@tau:tmp.Yboq6CCf$ ceylon compile-dart simple
Note: Created module simple/1.0.0

jvasileff@tau:tmp.Yboq6CCf$ ceylon assemble-dart --mode=js simple
